Energy medicine is one of the major categories of complementary and alternative
medicine (CAM). These therapies typically involve low-level energy field interactions.
They include human energy therapies, homeopathy, acupuncture, magnet therapy,
bioelectromagnetic therapy, electrodermal therapy, and phototherapy, among others.
Many of these modalities challenge the dominant biomedical paradigm because they
cannot be explained by the usual biochemical mechanisms. One possible influence of
biofield phenomena is that they may act directly on molecular structures, changing the
conformation of molecules in functionally significant ways. Another influence is that
they may transfer bioinformation carried by very small energy signals interacting
directly with the energy fields of life, which is more recently known as
the biofield (Rubik et al, 1994).
Moreover, other mysteries in biology and medicine exist that appear to involve
interacting energetic fields, including the mystery of regenerative healing in animals,
sometimes associated with innate electromagnetic energy fields that have been
measured (Becker, 1960, 1961) and sometimes actually stimulated with external low-
level energy fields (Becker, 1972; Smith, 1967). Another mystery is that living organisms
respond to extremely low-level nonionizing electromagnetic fields, displaying a variety
of effects ranging from cellular and subcellular scales to the level of brain, emotions, and
behavior. These fields may be beneficial (therapeutic), deleterious (electromagnetic
pollution), or neutral. Then, the mystery of embryonic development from the fertilized
egg to an organized integral animal should be considered, which may also involve innate
energy fields, starting with the initial polarization of the fertilized egg.
Although these phenomena involve an integral and dynamic wholeness that challenge
the power of molecular explanation, another biophysical view of life has been offered
that may help explain them. Living systems may be regarded as complex, nonlinear,
dynamic, self-organizing systems of energetic and field phenomena. At the highest level
of organization, each life form may possess an innate biologic field, or biofield, a
complex, dynamic, weak energy field involved in maintaining the integrity of the whole
organism, regulating its physiologic and biochemical responses, and integral to
development, healing, and regeneration (Rubik, 1993, 1997, 2002b).
Needless to say, the concept of an organizing field in biology and medicine evokes
shades of vitalism, an old philosophical concept in the West from the 1600s that was
overthrown in nineteenth-century science. In this view, the essence of life is seen as a
metaphysical, irreducible life force that cannot be measured. Indigenous systems of
healing such as Ayurvedic and Chinese medicine and modern modalities such as
chiropractic rest on concepts of a vital force or subtle life energy that is central to
healing. Called by many names, including prana in Ayurvedic medicine and qi in
Chinese medicine, these indigenous terms go back thousands of years. They may
actually refer to something similar to the present-day concept of the biofield, which is, at
least in part, based on the electromagnetic field theory of modern physics but, in
principle, might also include acoustic and possibly other subtler energy fields not yet
known to science. The important difference between traditional and modern views of
the vital force is that the biofield rests on physical principles and can be measured,
whereas the traditional concepts remain metaphysical. Nonetheless, considerable
similarities exist between ancient concepts of the life force and modern biofield concepts
in their assumption that a form of life-giving energy flows throughout the body and that
illness arises as a result of blockages, excesses, or irregularities in its flow.
Additionally, biofield therapies incorporate notions of a universal life energy, as in Reiki
(a form of Japanese spiritual healing), qigong therapy, and many other types of human
energy healing performed today. Many practitioners of biofield therapies can also assess
imbalances in the human biofield either with their hands or intuitively.
On the one hand, an organism is similar to a crystalline structure of ordered
biomolecules. On the other hand, the essence of life is more similar to a flame, burning
matter into energy and dancing not only with organized vitality, but also with an
element of unpredictability or chaos. Both views may be necessary to describe life in the
same way that, in quantum physics, both a particle view and a wave view are necessary
to describe fully the nature of light, as well as matter at the smallest scales. This dual
model in physics, popularized by the Copenhagen interpretation of quantum theory, is
called the principle of complementarity. Similarly, an energy field view of life may be
seen as complementary to the conventional biomolecular view rather than antagonistic.
The brain, for example, can be analyzed in terms of the receptors, neurotransmitters,
ion channels, and so forth that help explain neuronal firing; or it can be viewed in terms
of the oscillations of its neuronal circuits and the magnetic and electrical fields of its
continual activity, with possible regulatory feedback from the fields themselves. The
biophysical foundation of life, proposed here as the biofield, provides the rudiments of a
scientific foundation for understanding some of mysteries of life that remain and may
perhaps take us beyond into a new era of understanding life.
Electromagnetic Fields in Life
Electrical currents, along with their associated magnetic fields, can be found in the body
(Becker and Selden, 1985). The electrical and magnetic fields of the human body are
complex and dynamic and are associated with dynamical processes such as heart and
brain function, blood and lymph flow, ion transport across cell membranes, and many
other biologic processes on many different scales. These phenomena all contribute
various field components to the biofield.
In addition, a broad spectrum of radiant energies exists known as electromagnetic
waves, ranging from the ultra-low, extremely low, very-low, low, and medium broadcast
waves; very high – frequency broadcast waves; microwaves; infrared rays; visible light
rays; and even ultraviolet radiation, all emanating from the human body. The peak
intensity of the electromagnetic radiation of the human biofield is in the infrared region
of the electromagnetic spectrum, in the range of 4 to 20 microns in wavelength. The
belief is that much of this emission, particularly in the infrared region, is from thermal
effects associated with metabolism.
Human Biofield
The human body emits low-level light, heat, and acoustical energy; has electrical and
magnetic properties; and may also transduce energy that cannot be easily defined by
physics and chemistry. All of these emissions are part of the human energy field, also
called the biologic field, or biofield. However, no agreement has been reached in the
scientific community on the definition of the biofield. Various approaches have been
submitted by this author (Rubik, 1993, 1997, 2002b) and other authors [Popp (1996);
Tiller (1993); Welch (1992); Welch and Smith (1990); and Zhang (1995, 1996)]. Most
research has focused on electromagnetic aspects of the biofield. We restrict the rest of
this chapter to the electromagnetic portion of the human biofield where the main
scientific focus has been.
Biology has been preoccupied with its molecular revolution that focuses on structure-
function relationships in biochemistry. This effort culminated in the Human Genome
Project whereby teams of scientists from around the world mapped all the genes in
human deoxyribonucleic acid. Most of the scientific effort and funding remains in
molecular biology. By contrast, only a small number of scientists worldwide have
worked to understand the energy fields of the human body. Moreover, measuring the
biofield and understanding its role in life are more difficult than the study of more
tangible phenomena, and the funding for the former has been extremely scarce.
Therefore scientific advances in biofield research have been few, and biofield science
remains a frontier area ripe for exploration.
"If we try to pick out any thing by itself, we find it hitched to every thing else in the
universe"
~ John Muir, 1911
The biofield is also elusive. We cannot isolate it or analyze it comprehensively. As John
Muir wrote, "if we try to pick out any thing by itself, we find it hitched to every thing else
in the universe" (Muir, 1911). For a field, this connection is especially true, given that,
regardless of its source, it travels outwards to infinity, interacts with other fields by
superposition, and interacts with matter along the way. Additionally, phenomena such
as resonance can occur, involving an energetic coupling of, or oscillation within, matter.
The fields of the human body may also be influenced by the fields of nearby organisms,
the biosphere, and even the earth and cosmos, especially geocosmic rhythms. From a
theoretical perspective, we cannot calculate the human biofield from first principles
because of its dynamic aspects and enormous complexity. Nonetheless, we can measure
certain aspects of the biofield and observe its footprints via novel technologies.
The human biofield may carry novel information of diagnostic and predictive value for
medicine. Thus new technologic developments and methodologic improvements in
measuring the biofield should be a central aim of health-related research. By measuring
various aspects of the biofield, we may be able to recognize organ and tissue
dysfunctions even in advance of diseases or symptoms and treat them appropriately so
as to eradicate them. We may also be able to use biofield measurements to predict
whether the effect of a particular course of therapy will be effective or ineffective,
depending on whether it improves or thwarts the biofield. This possibility is especially
true for the CAM therapies, which, in principal, often evoke a shift in response to
extremely small stimuli that harmoniously work with the human body’s natural
dynamics to restore balance.
Conventional Measures of the Human Biofield Used in Science and Medicine
Some of the field emissions from the body are the basis of many technologies commonly
used in clinical diagnosis and research. Thus a significant number of conventional
medical tests already provide windows into the human biofield.
Conventional science and medicine have long used the electrocardiogram (ECG) and the
electroencephalogram (EEG) to assess physiologic function of heart and brain,
respectively. The heart produces coherent contraction of numerous muscle cells,
resulting in vigorous electrical activity. In fact, the heart makes the greatest contribution
to the electromagnetic, as well as the acoustic, human biofield. The brain’s activity
contributes to a lesser extent to the biofield because its field emission is weaker than
that of the heart. The ECG was first developed in 1887 and records the electrical activity
from different areas of the heart. The EEG was developed in 1875 and records electrical
activity from the various brain regions by using multiple electrodes on the head. In
addition, corresponding magnetic field measurements of the heart and brain have been
discovered, which are the magnetocardiogram (MCG) and the magnetoencephalogram
(MEG), respectively. However, the magnetic fields of the body are very low level and
typically require specialized equipment such as super-conducting quantum interference
devices (SQUIDs) that are expensive to operate. Nonetheless, such magnetic field
measurements of the body reveal more information than the electrical measurements,
especially if coupled with three-dimensional resolution, as in the case of MEG. For the
latter, localizing the activity of a region of the brain approximately the size of a pea is
possible. Additionally, some of the more recently developed medical scans, such as
functional magnetic resonance imaging and positron emission tomography, can also be
used as indirect indicators of electromagnetic activity.
Galvanic skin response (GSR) measures the electrical conductance between two
electrodes placed on the skin. This value is a mainstream measure used in lie detectors
to help determine veracity and in biofeedback technology to help promote relaxation.
The human body is a strong emitter of infrared radiation, on the order of 100 watts, and
visualization of this emission is used in medical imaging. Thermography uses an
infrared camera and an associated software system to visualize the pattern of infrared
emission, which we cannot see directly but experience as heat. This method can detect
changes as small as 0.01° C in the human body. Thermography can detect acute and
chronic inflammatory conditions. This method is documented by many research studies
to show toxic accumulations, tumors, and other diseases, often much earlier than x-ray
mammography or other imaging procedures, for example, in the case of breast
thermography (Amalu et al, 2006). Typically, thermography is used to locate hot spots
and left-right imbalances that correspond to problem areas. However, the actual
temperature and emissions pertaining to the infrared portion of the human biofield
have been considered much less important thus far to clinicians and investigators.
Thermography is also used before and after therapy to visualize its influence, as for
example in the case of infrared photonic treatment to look for improvements in the
symmetry of the emission patterns after treatment. Thermography is now an accepted
diagnostic procedure in medicine.
In this chapter, no further effort to discuss these conventional measurements will be
made. Instead, we will focus on other ways of assessing other components of the human
biofield, in particular, such as the energetic systems that may be associated with a subtle
life energy or vital force important in self-healing, such as the acupuncture meridian
system and the system of the chakras. These methods represent frontier assessment
measures and are not yet part of mainstream science or medicine. Nonetheless, they are
often of great interest in CAM and integrative medicine.
New Approaches to Measuring the Human Biofield
If a Human Energy Project were to exist to measure all of the electromagnetic
components of the human biofield, akin to the Human Genome Project, we would need
teams of scientists measuring the emissions at the various frequency bandwidths using a
plethora of detectors and measurement devices. This effort would involve measuring
different frequency bands within the electromagnetic spectrum emanating from the
body ( Figure 20-1 ).
Figure 20-1. The electromagnetic spectrum showing all the known radiant
electromagnetic energies.
It includes the full range of nonionizing energies, as well as visible and ultraviolet light,
which are ionizing radiation. This spectral range is enormous. In some of these spectral
regions, such as the infrared, as mentioned previously, the human body emits relatively
high- intensity radiation, whereas in other regions, such as the visible spectrum, the
body emits extremely low-intensity light radiation on the order of a few hundred
photons per second per square centimeter surface area. Figure 20-2 shows the power
spectrum of human emission (Bembenek, 1998).
Figure 20-2. The power spectrum of the human body emission.
In foundational research for CAM, more interest has occurred in measuring regions of
the human emission spectrum that are unrelated to thermal excitations of biomolecules,
as in the case of visible light. Some researchers speculate that the extremely low-level
visible light emission from organisms, called biophotons, may be coherent (as in a laser)
and may communicate key electromagnetic bioinformation (Chwirot et al, 1987; Popp,
1992, 1998). Some of this research and its possible applications will be described. That
such biophoton emission may mediate certain biofield therapies is also possible.
Additionally, the induced light emission that is measured as the Kirlian effect from high-
voltage electrophotography will also be discussed.
Although we may be able to measure various frequencies of electromagnetic radiation
from the human body, these measurements in themselves do not reveal whether the
energy is (a) important to life, (b) waste energy, or (c) noise in the system. One way of
assessing the components of the biofield that may be central to the living state and
especially to healing is to study the therapeutic modalities that apparently employ the
practitioner’s biofield: the biofield therapies, such as therapeutic touch, Reiki, Johrei,
external qi therapy, and polarity therapy. In most of these modalities, practitioners
begin their patient treatment by sensing imbalances in patient biofields and then work
to improve their energy regulation by transmitting energy to them, all through the use of
their hands. A small but growing body of scientific evidence has been uncovered that
biofield therapies show positive physical changes on living systems. In fact, some of the
scientific evidence for the biofield and its importance in health and healing comes
indirectly from these studies that assess the effects of these biofield therapies on
humans and other living systems. More direct evidence of the biofield has been gathered
by measuring changes in the practitioner’s or the patient’s biofield before and after
biofield therapy or before and after other energy medicine interventions.
We will summarize some of the key findings on biofield therapy that show effects on
target systems in the laboratory. These are, in the more literal sense of the term,
bioassays, which may help elucidate the key life-stimulating components of the human
biofield and the action of these components at the cellular and biochemical levels.
In summary, various strategies for measuring the human biofield include measurements
of biophoton emission, as well as induced light emission; measurements on
practitioners performing biofield therapy and on patients receiving biofield therapy; and
bioassays for biofield therapy, as mentioned previously. Additionally, measurements of
the electric or magnetic fields (or both) directly from the human body, especially from
the acupuncture points, have also been developed.
Besides the veritable energies of the biofield discussed thus far, the human biofield may
also consist of other putative energies as well, more subtle than the energy fields
presently known in physics. In relation to this possibility is a less common form of
therapy known asdistant healing, in which the practitioner and patient are in different
locations, ranging from many feet to many miles away. Invoking electromagnetic fields
as causal in distant healing is impossible because electromagnetic energies diminish
rapidly over distance, varying as the inverse of the square of the distance. Nonetheless,
many biofield practitioners, including Reiki and external qi therapists, often learn and
practice both local and distant healing. Distant healing, which is often combined with
spiritual healing and prayer, may involve no energy transfer whatsoever if it occurs by
the principle of quantum nonlocality, or it may involve a putative energy not yet
identified in science. However, in this chapter, we will address only specific aspects of
the human biofield that are tangible and can be measured. We will also focus only on
local biofield therapy.
Devices and Techniques Used to Measure the Biofield
Various devices have been developed that claim to assess aspects of the biofield, most of
them electromagnetic in nature. That this area of research is in its infancy, with
inadequate funding, no ongoing government sponsorship, and developed by a small
number of people working largely in isolation, must be pointed out. Thus, not
surprisingly, several issues remain to be resolved.
Here, we describe a few of the devices and techniques that are being used in biofield
research or the clinic that appear promising but that need further substantiation to
become accepted. These techniques fall into three categories: (1) high-voltage
electrophotography, (2) acupuncture point conductivity measurements, (3) and
biophoton measurements.
High-Voltage Electrophotography: the Gas Discharge Visualization Camera
The gas discharge visualization (GDV) camera, developed by the Dr. Korotkov Co., St.
Petersburg, Russia, is perhaps the best-known form of contemporary high-voltage
electrophotography based on the Kirlian effect (Kirlian and Kirlian, 1961) and was first
discovered in Russia in 1948. Kirlian photography was not introduced to the West until
the 1970s because of communication difficulties during the Cold War. This digital
camera, introduced in the West in the late 1990s by its inventor, physicist Dr.
Konstantin Korotkov, comes with software and offers the advantage of using a lower
voltage than conventional Kirlian photography that is not felt as an electric shock by
subjects. A photograph of one of the recent GDV models is shown in Figure 20-3.
Figure 20-3. Photograph of the gas discharge visualization (GDV) camera.
Although scientists never widely embraced the Kirlian technique, research was
conducted (Boyers and Tiller, 1973; Krippner and Rubin, 1973) and culminated in the
founding of the International Kirlian Research Association in the United States in 1976,
no longer in existence. Perhaps the most famous experiment is the phantom leaf effect,
whereby electrophotography on a segment of a leaf yields a photograph showing the
whole (Moss, 1979). Replication of this effect has been achieved but with great difficulty
(Korotkov, personal communication, 2002). The Kirlian technique was used clinically in
Germany for decades, and the Vega-Grieshaber Company manufactured cameras to
record the Kirlian emission of hands and feet. In this setting, energy emission analysis
on patients was developed by Peter Mandel, who documented many clinical cases
(Mandel, 1986).
The GDV camera uses pulses (10-microsecond) of high-frequency (1024 Hz), high-
voltage electricity (10-15 kV) that is selectable from several ranges. The time exposure of
the sample is selectable from 0.5 to 30 seconds. In addition to still digital photography,
recording digital video is also possible for up to 30 seconds. A charge-coupled detector
(CCD), which is a standard detector of low-level visible light used in telescopes and
other scientific instruments, detects the pattern of photons emitted from each fingertip.
This information is sent by cable to a computer for analysis, as shown in Figure 20-4 .
Figure 20-4. Schematic setup of the GDV camera.
The method of use is as follows. The subject sits or stands in front of the camera and is
prompted by the researcher to place a given fingertip, one at a time, on the electrified
glass plate of the camera, under a lens cover with a special port for the finger, to
maintain ambient darkness. The researcher pushes a mouse button attached to both the
computer and camera to activate the camera, which sends a pulsed electric field to the
plate for the selected time duration. When each fingertip is thus electrified, it emits a
corona discharge of light that is then captured by the GDV capture program.
An example of the raw data, a single GDV image from a single finger, is shown in Figure
20-5 . The reader should note that the CCD does not distinguish color; thus the captured
GDV images appear black and white.
Figure 20-5. GDV photograph of corona discharge from human thumb, raw data.
Theoretical considerations suggest that the GDV images of the fingertips are a complex
mixture of a correlate of the biofield plus additional effects. The human subject may be
considered as part of a large electrical circuit in the GDV technique. The discharge of
light from the finger is the result of a glowing gas plasma of charged particles from the
finger to the plate that conducts electricity. This discharge results from a combination of
local and global effects from the human subject. Local effects include local skin
conductivity and perspiration. The global effects are associated with whole body
contributions, including biofield elements such as the acupuncture meridians, which
also relate to the common impedance of the body from all the organs and tissues (
Figure 20-6 ).
Figure 20-6. Global and local factors in GDV photographs of finger emissions.
The relative contribution of each of these contributing factors to the GDV images for a
particular subject is impossible to determine. However, if one uses the GDV camera to
make images before and after an intervention and observes the differences between the
before and after images, then the geometric effects of local skin conductivity and
common impedance remain relatively constant, whereas the perspiration and the whole
body contribution correlated with biofield will be the changing factors contributing to
any observed differences. Moreover, if one makes GDV images with and without using
the GDV filters, which are very thin polyethylene filters that apparently block the effects
of perspiration that also contribute to the induced light emission, then one may, in
theory, filter out the local perspiration effects and primarily observe the whole-body
contribution. An important point to note is that the GDV images are induced light, not
natural light, emitted from the body; thus their exact relationship to the natural field of
the body, the biofield, are unclear. Nonetheless, meaningful results have been shown in
some studies, consistent with improved energy regulation, for example, after qigong,
and which are also consistent with measurements from using other types of biofield
instrumentation.
Figure 20-7. Finger emission sector analysis used in GDV software.
Besides the GDV capture program, other GDV software modules have been developed
that work in tandem to assess various parameters of the emission patterns, including
area, intensity, density, and fractality, as well as details of various sectors of the fingertip
patterns that purportedly relate to the bioenergetics of specific organs and organ
systems ( Figure 20-7 ) (Korotkov, 2002). A sample organ diagram is shown in Figure
20-8.
Figure 20-8. Sample organ diagram generated by GDV software, showing the
consistency of repeated measurements on different days for a normal person.
The inventor, Konstantin Korotkov, PhD, has reported some standardization of
techniques to show the stability and reliability of the GDV parameters (Korotkov, 1999,
2002). Moreover, empirical data showing a correlation between particular sectors of
fingertip emissions and diseased organs was published independently by Peter Mandel
who studied numerous patients over decades using the older form of Kirlian
photography with photographic film (Mandel, 1986). The evaluation of the fingertip
sectors and their comparison with particular organs and tissues in the GDV software is
said to be based on both the system of acupuncture meridians and su jok (a form of
Korean hand acupuncture) (Korotkov, 1999). The assignment of the various fingertip
sectors to the seven chakras is offered in a chakra diagram ( Figure 20-9 ) (Korotkov,
2002), but the detailed calculations to define values on the chakra diagram are not
reported. A sample chakra diagram is shown in Figure 20-10.
Figure 20-9. Assignment of finger emission sectors to generate chakra diagram in GDV
software, in which fingers 1, 2, 3, and so forth refer to the thumb, index finger, middle
finger, and so forth.
Figure 20-10. Sample chakra diagram generated by GDV software.
The software analyses most useful for researchers, as their algorithms are fully revealed,
include the basic parametric calculations derived from the raw data, whereby each
finger emission pattern is analyzed for the total and normalized area of illumination,
brightness, fractal dimensionality, and density. Each of these parameters is defined by
mathematical equations (Korotkov, 2002), thus they have clear objective meaning. An
example of a study in which such parametric calculations were made is one exploring
how performing qigong influences the GDV images of 16 adult subjects (Rubik and
Brooks, 2005). All 10 fingers of each of the adults were assessed using the GDV camera
immediately before and after performing Dayan (wild goose) qigong in a group setting.
One main observation is that the density parameter increased (p<.01) after qigong,
which means that a more uniform circle of light was emitted from the subjects’
fingertips after qigong. Another observation is that the emission patterns from the 10
fingers of each subject showed decreased variability after qigong. These results are
consistent with the expectation in oriental medicine that better regulation of qi results
from practicing qigong, with qi flowing in a smooth unimpeded manner throughout the
body. Although we cannot and may never be able to measure the flow of qi per se, the
greater uniformity observed in the GDV images is suggestive of improved energy
regulation.
Using a quantum-biophysical model of entropy and information flows and supported by
some clinical data, Korotkov, Williams, and Wisneski (2004) advance the concept that
the GDV technique provides indirect information about the level of free energy
resources (excited electronic states) available in protein complexes in the body.
Additionally, Korotkov together with colleagues have published several experimental
research papers using the GDV technique in English (and others in Russian) on a wide
range of applications to humans, including direct vision (visual perception by means
other than through the eyes) (Korotkov et al, 2005), on altered states of consciousness
(Bundzen et al, 2002), and in cosmetology (Vainshelboim et al, 2004). Other
researchers have proposed the utility of the GDV technique as a holistic medical
screening method (Chiang, Wah Khong, and Ghista, 2005).
The GDV technique has been used for clinical studies mainly in Russia (Bevk,
Kononenko, and Zrimek, 2000), where it is a registered medical device. It has also been
used to monitor the results of stress-management training (Dobson and O’Keffe, 2000).
Several studies by other researchers have been performed that explore the usefulness for
whole body assessment of human subjects subjects (Rubik, 2002a). Other researchers
have used similar high-voltage electrophotographic techniques (not the GDV camera,
however) to investigate the reproducibility of assessments of biofield practitioners
compared with controls with significant results (Russo et al, 2001). One result observed
is that biofield practitioners were able to change their corona discharge parameters by
the intent to emit energy, whereas controls were not.
Some words of caution are necessary for future researchers hoping to gather meaningful
data using the GDV technique. Careful placement of each finger with light steady
pressure on the camera plate is important. Collecting data at the same time of day each
day for comparison purposes is also important because of the circadian rhythms in the
flow of qi in the meridians. In this way, each human subject can be viewed as having a
unique energetic signature in GDV images that is consistent from day to day in adults
who are healthy and not receiving therapeutic treatments. New investigators should
work to establish this reliability in their data before venturing to conduct studies with
the GDV. All devices, including the GDV, provide useful information about the subject in
ways that are necessarily limited by the technique, skill, and level of interpretation of the
user. Using and interpreting the GDV data requires experience. New users will find that
interpreting the results is challenging. In the current state of the art, investigators are on
their own in their interpretation of their data, given that no standardized basis for
interpreting findings has been established.
Some limitations exist that are specific to the GDV technique. One limitation is that it
measures induced light produced by electrifying the person’s finger. The relationship
between this induced emission and the extremely low – level natural light of the
endogenous biofield is unknown. A second limitation is that, for the human being, the
GDV can measure emission only from the fingertips. The software employs various
conceptual and mathematical frameworks to apply the data to modeling of energy flow
within the tissues, organs, and whole body. Such frameworks include algorithms of
oriental medical systems such as the various acupuncture meridian systems and su jok,
in which the hand is a homunculus of the whole body. However, the algorithms for these
extrapolations from the data are not fully revealed. A third limitation is that the glass
plate of the camera will not permit any ultraviolet light in the emission to be detected,
given that glass blocks ultraviolet radiation. However, in some cases, for example, in
certain altered states of consciousness, the emission patterns become ultraviolet. A
fourth limitation, mentioned earlier, is the absence of a large database of human
fingertip data correlated with states of health, specific diseases, and so forth; therefore
people using this device must use subjective means or develop their own database for
data interpretation. A documented database and device standardization needs to be
published in peer-reviewed journals to make that the GDV camera is a truly scientific
instrument. A fifth problem for research is the many different models of the GDV
camera, without any attention to model numbers or the manufacturer revealing the
differences between the models. Researchers who possess more than a single version of
these devices have noted differences in results obtained with the various models.
Therefore a lack of standardization appears to exist.
No reliability studies have been published on the use of the GDV camera. However, one
study on reliability on a related technique showed moderate reliability (Treugut et al,
1998).
In conclusion, the GDV and related techniques appear to be able to measure certain
aspects of biologically generated electromagnetic fields contained within the corona
discharge that are relevant for CAM. However, a concerted effort is needed to delineate
and resolve the various issues described previously so as to advance the use of this
method for biofield science.
Acupuncture Point Conductivity Measurements
A considerable number of devices are available today that use a method of assessing
electrical conductivity of the skin through the acupuncture meridian system for the
purpose of providing information about the energy flow related to the health of the
body. This technique is known by various names, including electrodermal screening
(EDS), electrodermal testing (EDT), and electroacupuncture according to Voll (EAV). In
the United States, many of these electrodermal devices have been categorized by the
U.S. Food and Drug Administration as biofeedback devices for meridian stress and more
recently referred to as devices for meridian stress assessment (MSA) and living systems
information biofeedback (LSIB). Just as electrical conductivity measurements provide
biofeedback on a patient’s nervous state to practitioners using GSR, EDS devices
provide direct biofeedback or information on the biofield status or response of the
patient. One main use for these devices in the West is allergy testing, although they are
used for a variety of other purposes as well, including oriental medicine evaluation.
Various corporations market these devices, including Vega, Biomeridian, and Health
Epoch, to name a few.
In 1950, Reinhold Voll, a German physician, was studying the acupuncture meridian
system. He reasoned that if acupuncture points were portals on the skin for channels of
qi running through the body, then measuring this energy at the acupuncture points
should be possible. Voll constructed a device to locate the acupuncture points by virtue
of their greater electrical conductivity compared with the surrounding skin. He found
correlations between disease states and changes in the electrical properties of the
various acupuncture meridian points (Voll, 1975). Furthermore, Voll made two
discoveries:
1. Indicator drop. Voll compared the acupuncture point measurements of healthy
patients with those of patients who had conventionally diagnosed diseases. He found
that the electrical conductivity of healthy acupuncture points measured were within a
given normal range, whereas readings outside of this range revealed disturbances in the
tissues and organs sometimes associated with these points. In addition, Voll noticed that
major disturbances in the body produced a downward drop, or steady decay, of the
conductivity indicator as the point was being measured. This effect became known as
the indicator drop (Voll, 1975).
2. Medication test. Voll discovered by chance that closed bottles of medicines placed
in the proximity of the patient could change acupuncture point conductivity values
(Voll, 1977). This test became known as the medication test. Such testing may provide
useful diagnostic or therapeutic information. Apparently, substances such as
homeopathics in the vicinity of the human subject may alter the subject’s biofield by
means of a resonance phenomenon. However, no consensus has been reached on the
modus operandi for such an effect.
Many case reports documenting the success of EDS have been published. In addition, a
few published studies have documented physiologic correlates or patient outcome (or
both) for certain medical applications of EDS. Sullivan and colleagues at the University
of California Los Angeles reported that patients with lung disease confirmed by x-ray
examination had 30% lower electrical conductivity readings taken at acupuncture lung
points than those of healthy patients. An 87% correlation was found between the testing
results for the lung points and the x-ray testing for lung cancer, whereas no correlation
was found for small intestine acupuncture points (Sullivan et al, 1985). Lam and Tsuei
at the University of Hawaii have published approximately two dozen papers establishing
the correspondence of EAV readings with physiologic disturbances. In one study, the
authors showed that in the treatment of diabetes, EDS was a beneficial adjunct to the
conventional diagnostics in determining the proper allopathic doses of insulin and
glyburide, as well as homeopathic remedies and nosodes (Lam, Tsuei, and Zhao, 1990).
In a double-blind study on allergy testing, six different diagnostic methods for allergy
testing were compared—history, food challenge, skin testing, radioallergosorbent test,
immunoglobulin E antibodies, and EDS—on 30 subjects. In over 300 tests, EDS
matched the history 74% of the time and was most compatible with the food challenge
test, which is considered to be the most sensitive of all tests for food allergy (Tsuei et al,
1984). Use of EDS is greater outside the United States, and much of the literature on it
has been published in German, French, Japanese, and Chinese.
Many different types of EDS devices and associated measurement techniques have been
developed. However, two main schools of EDS have been established, which we refer to
here as the Western and Eastern schools.
The Western school evolved in Germany through three main phases: EAV, bioelectronic
functions diagnosis (BFD), and the VEGA resonance test (VRT) (Rademacher and
Wesener, 1999). The first commercially produced EAV instrument in Germany was the
Dermatron, manufactured by Pitterling Electronics GmbH in 1956. EAV was a laborious
procedure that involved testing hundreds of points on a person. BFD simplified the EAV
procedure; it introduced silver electrodes that conduct electricity better than the brass
used in EAV, it introduced a sector measurement to assess any blockages in regions of
the body, and it used only a few dozen acupuncture points on the hands and feet. BFD
practitioners soon discovered that a single acupuncture point could be used for all
testing, which made the procedure much faster and easier to use. This discovery led to
the VRT and a new device designed in 1978 by Helmut Schimmel, MD, DDS, together
with VRT. The Western style EDS devices are tools that can access aspects of the body’s
biofield control system and communicate with it to obtain answers about the patient’s
sensitivity to and need for nutritionals, remedies, and environmental substances. By
these means, EDS may help diagnose conditions and diseases because it provides a
highly individualized way to pose questions of the patient’s condition and obtain
answers at the energetic level.
In contrast, the Eastern school of EDS devices draw on Ryodaraku theory from
traditional oriental medicine. This theory was developed by Yoshio Nakatani in Japan in
1949. It is based on the principle that disease is thought to be reflected by the 12 source
acupuncture points (Oda, 1989). If excess energy is being conducted at a given point, it
is called excitation (fullness), and if a lack of energy exists, then it is called inhibition
(emptiness). This discrepancy or inconsistency among the meridians that indicates
excess excitation and inhibition causes illness. Nakatani also discovered age, gender,
and seasonal variations in the conductivity values and that when the values are generally
higher, the subject’s autonomic nervous system is hyperaroused.
The Voll and Ryodoraku methods use almost the same technique of checking the
indicator drop conductivity value of each acupuncture point. However, the two schools
typically measure different points. Normally, the Voll school measures some 40 points
that are different from the 24 points measured in Ryodoraku. Moreover, the Voll
method is more organ based than meridian based. The Voll method uses measurements
at acupuncture points for bioinformational purposes and has narrowed its focus down to
a small number of these points using a distinctly Western orientation to health and
disease, including use of homeopathy in many of the test remedies. By contrast, the
Ryodoraku method assesses meridian stress according to oriental medicine principles.
For example, in Chinese medicine, an abnormal liver meridian does not necessarily
mean that the liver organ itself is abnormal; rather, it refers to a primary energetic
imbalance.
One quality device that is based on the Ryodoraku method is the Electro-Meridian
Assessment System (EMAS). No training in acupuncture is required to use this system.
The device is easy to learn and operate even for beginners. Made by Health Epoch, Inc.,
the EMAS is composed of a portable measuring device and application software. The
electrical conductivity of the 12 source acupuncture points of the body, on the left and
right side, is measured, and the resulting values are analyzed by the software package in
multiple ways according to the different schools of oriental medicine.
Figure 20-11. Schematic setup of the Electro-Meridian Assessment System (EMAS).
The EMAS device is essentially a computer card housed in a metal casing that connects
to a computer universal serial bus port and an alternating current (AC) power outlet (
Figure 20-11 ).
The probe, which is attached to the device via electrical cables, is a 1-cm round, hollow
metal, spring-loaded device with a plastic handle. In addition, the patient holds a
grounding rod in the opposite hand during measurement ( Figure 20-12 ).
Figure 20-12. Photograph showing subject undergoing mea-surement using the EMAS.
The constant-pressure probe ensures measurement stability and is fitted with a ball of
cotton saturated with saline solution for optimal conduction. A simple automatic
calibration is performed to ensure the accuracy of the EMAS system just before
measuring a subject. When properly calibrated, the maximal current entering the
subject’s body is 200 microamperes, for which 95% of subjects experience no sensation
during measurement. The practitioner is then prompted by the software precisely where
to position the probe on the subject’s body for each point measurement in a sequence
from the left to the right hand and then from the left to the right foot. The practitioner
manually holds the probe in place while the electrical conductivity is assessed at each
point. The measurement of all the points takes approximately 5 minutes. After the final
measurements are obtained and the data are saved, the software immediately displays
the resulting bar chart of meridian conductivities ( Figure 20-13 ).
Figure 20-13. Example of the bar chart showing the 24 acupuncture point conductivity
values generated by EMAS software.
Normal values are shown with green bars, tolerable values in yellow, and abnormal
readings in red bars. At a glance, the practitioner can note which meridians are
unbalanced. Other analyses of the data can be made, depicted on subsequent screens in
the software (not shown here), including the average body energy or overall qi, the
upper and lower body energy ratio (hands vs. feet), the left and right side energy ratio,
the internal (yin) and external (yang) energy ratio, and the autonomic nerve ratio. The
software produces a report showing the results for a given patient, which also suggests
different types of treatment, including different styles of acupuncture, acupressure,
aromatherapy, Chinese herbs, dietary recommendations, and more. Although the EMAS
is primarily designed for clinical practice, it can also serve as a useful tool for research in
biofield science. It is particular well suited for investigating the before and after effects
of any intervention on the acupuncture meridian system; it also provides a detailed view
of the human energy system from the perspective of several different oriental medicine
systems, which is unique. A small number of studies using the Ryodoraku method have
been published in English (Sancier, 2003; Schmidt et al, 2002).
In summary, all EDS machines measure the body’s electrical conductivity. Although
different electrode specifications and measurement parameters may be used by various
manufacturers, the goal is the same—to assess the health of the body through its ability
to conduct microcurrent. Simply stated, healthy bodies conduct microcurrent more
readily and more uniformly than unhealthy ones.
Many advantages have been discovered to using EDS over other evaluation methods,
such as its speed of use, individualized approach to care, and the fact that it is
inexpensive relative to conventional biomedical testing. However, new users of the
Western-type EDS may find that training by qualified teachers, as well as considerable
time to learn and to practice on their own until they feel confident to use it clinically, is
required, although the newer devices are easier to use than the older ones. The
practitioner must learn how to manipulate the probe and how to find the acupuncture
points and in what sequence to do the testing. Many practitioners who learn this
technique find that it can transform their practice in that they have consistent, positive
results with patients and come to rely on it. EDS is particularly useful for functional
medicine—a type of CAM in which individualized assessment and early intervention are
used to improve physical, mental, and emotional function. Such is the case in both the
Eastern and the Western methods.
Research is needed to gain understanding of the significance and interpretations of EDS
measurements of conductivity and, more fundamentally, of the responsiveness and
possible causal role of the acupuncture meridian system in relation to health status.
Most importantly, nobody fully understands how dysfunction or disease correlates with
the electrical conductivity of certain points on the skin in a consistent way, although this
correlation has been empirically observed by many researchers and clinicians
worldwide. More basic research in this area, plus further studies that would extend the
validation of the EDS, is recommended
The accuracy of EDS measurements may be somewhat dependent on the practitioner’s
skill and technique, as associated, for example, with calibrating the instrument, placing
the probe properly on the acupuncture point, maintaining consistent pressure with the
probe, avoiding physical contact with the patient except at the measurement point to
minimize energetic interactions, and the consistency of procedure throughout the
measurement process. New probes should be studied to evaluate their precision,
reliability, and operator dependence relative to older probes. Further reliability studies
are also needed for this technology, especially given that electrical stimulation at the
acupuncture points associated with measurements may alter the bioenergetics of the
body, possibly jeopardizing the consistency of repeated measurements over short
periods.
A main obstacle to the acceptance of EDS is an attitude on the part of the conventional
medical community that has historical origins. Back in the 1800s, the use of electricity
in medicine was widespread. Around 1900, a large number of medical practices came
into question, and the Carnegie Foundation established a commission headed by
Abraham Flexner to investigate. The report, published in 1910, became widely known as
the Flexner Report and produced widespread changes in medical practice and medical
education. Electrotherapy disappeared from medicine and became regarded as
quackery. Nearly a century later, in an age of pharmaceutical dominance, the medical
community is still largely suspicious about EDS, despite the growing use of this modality
in CAM.
Biophoton Measurements
A substantial body of research exists on ultra-weak light emission from various
organisms (Cohen and Popp, 1997; Devaraj, Usa, and Inaba, 1997), including humans
(Van Wijk and Van Wijk, 2005). This type of energy is extremely low level, but it can
today be accurately measured with sophisticated instrumentation that is generally
customized (Lin et al, 2006; Van Wijk and Van Wijk, 2005). Systematic measurements
of this extremely weak light emission from the body, the waveband of which is in the
visible range from 400 to 720 nm in wavelength, represent one approach to assessing
the radiant nonthermal human biofield. This range might be correlated, as expected, to
changes in health, disease, healing, and altered states of consciousness, according to the
biofield hypothesis.
The investigation of light emission from organisms began with discoveries of Gurvich
(1874-1954) who noted that mitosis was stimulated in regions of onion roots exposed to
one another through a quartz barrier by what he proposed to be mitogenetic radiation.
He also identified secondary emission, by which regions of the organism receiving
mitogenetic radiation emit light, and a third phenomenon, known as the degradation
effect, which refers to the burst of light released when living organisms are damaged or
exposed to toxins (Gurvich, 1959). Gurvich also postulated the morphogenetic field
theory of life (Lipkind, 1987), a precursor to Sheldrake’s (1981) morphogenetic field
concept and the modern biofield hypothesis (Rubik, 2002 ). He regarded the biologic
radiations that he investigated as support for his theory of a deeper collective order in
the regulation of the organism.
Research in this area advanced when low-level light detection technology improved in
the 1950s and 1960s such that the ultra-weak emission from organisms, which ranges
from a few to hundreds of photons per second per square centimeter of tissue could, in
fact, be measured. Early systematic measurements of human biophotons attempted to
record the radiation from naked subjects with photomultiplier tubes and found that the
noise in the detector was approximately the same order of magnitude as the signal.
Nonetheless, researchers were able to integrate the signal over time and then found it to
be statistically significant over the noise. In related experiments, subjects were actually
asked to increase their light emission, and an increase in the signal was found to be
significant over controls (Dobrin et al, 1975, 1979). Using coolant ( – 23° C) to reduce
the noise of the photomultiplier detector, Edwards and colleagues (1989, 1990) counted
photons over time from body regions. The authors found that the abdomen, lower back,
and chest emitted from 4 to 7 photons per second, whereas emission from the forehead
and hand were larger, on the order of approximately 20 photons per second.
Furthermore, if a tourniquet were tied around the upper arm, the photon emission of
that palm of the hand was reduced 15%.
Three types of systems are presently used to measure biophotons: (1) photomultiplier
tubes, cooled down to minimize their noise, which register photon counts over time; (2)
a spectral analysis system, using a set of cut-off optical filters to determine the
wavelength characteristics of the emitted light; (3) and a two-dimensional system of
sensitive photon-counting devices, including arrays of cooled photomultipliers and
CCDs that produce biophoton images (Van Wijk and Van Wijk, 2005).
In 1993, Popp and colleagues in Germany created a special darkroom with a cooled
photomultiplier that could be moved around to scan the whole body of a subject lying on
a bed below. Two hundred persons were measured. The results show that biophoton
emission reflects (1) the left-right symmetry of the human body; (2) biologic rhythms
such as 14 days, 1 month, 3 months, and 9 months; (3) disease states reflected in the
broken symmetry between the left and right side of the body; and (4) light channels in
the body, which are hypothesized to regulate energy and information transfer between
different parts of the body. One main aim of Popp’s continuing human studies is to
identify specific regions of the body, the emission characteristics of which might
differentiate states of health and disease in an integral way (Cohen and Popp, 1997,
2003).
The relationship of biophoton emission to oriental medicine has been investigated
through several studies. In one study done in Korea, biophoton emission counts from
the dorsal and ventral sides of the hands of three healthy human subjects were
measured for 52 weeks. Results show that the emission rates were lowest in autumn.
Although the emission rates from the palms remain rather stable throughout the year,
those from the dorsa vary widely, depending on the season (Jung et al, 2005). In
another Korean study, left-right biophoton asymmetry from the hands of seven patients
with hemiparesis was studied. Findings revealed that the patients with left hemiparesis
emit more biophotons from the right than from the left hands, whereas the opposite was
found for the patients with right hemiparesis. Acupuncture treatment dramatically
reduced the left-right asymmetry of biophoton emission (Jung et al, 2003). Another
study showed that significantly more emission was recorded from the fingernails than
the fingerprints for each subject’s fingers (Kim et al, 2002). Still other studies suggest
that the biophoton emission from the acupuncture points is generally higher than that of
the surrounding skin (Inaba, 2000). Moreover, needling or using other means of
stimulating the acupuncture point enhances the emission over that of other acupuncture
points (Inaba, 1998). Inaba also used a system of two-dimensional photomultipliers to
record the two-dimensional pattern of biophotons from the surface of the hands. He
showed that the index and middle fingers of a subject had the highest intensity (Usa et
al, 1991). Interestingly, these two fingers are considered the sword fingers in certain
styles of qigong and are sometimes considered to be the chief emitting fingers in giving
external qi.
The biophoton emission from humans in studies on consciousness has also been
investigated. In eight subjects, Vekaria (2003) investigated the influence of intention to
change one’s emission on the measured biophoton emission and found that the mean
photon count decreased, but not all subjects were able to achieve this change.
Measurements made from the hands and foreheads of five meditators showed that
biophoton emission decreased after meditation (Van Wijk and Ackerman; Van Wijk,
2005). Another study of transcendental meditation (TM) subjects in particular showed
that regular meditators have the lowest biophoton counts and that biophoton emissions
of meditators and controls did not vary much in anatomic distribution, except for the
throat and the palm of the hand (Van Wijk et al, 2006). Because free-radical reactions
are thought to be responsible, at least in part, for the biophoton emission, the results
also suggest that TM helps reduce free-radical reactions in the body.
Two schools of interpretation of biophoton emission exist that reflect the age-old
struggle between vitalism and mechanism. One school is the chemiluminescence school,
which holds that the ultra-weak emission from life can be understood solely in terms of
known principles of chemiluminescence from free radicals as a byproduct of cellular
chemistry and that such light emitted is from random processes and thus carries no
signal. The other school, which we term here the biophysical school, retains the Gurvich
heritage and maintains that the organism is a radiator and antenna of a particular range
of electromagnetic frequencies or biophotons that are coherent (in phase) and are used
for communication, growth, and regulation in the living state. Long-range coherent
interactions in living systems are also expected from other physical considerations
(Frohlich, 1968). Liboff (2004) also wrote of the electromagnetic unity of the organism.
Several researchers have hypothesized that the electromagnetic field emission from the
human body is, at least in part, coherent and can carry information that is involved in
organizing biomolecular processes (Inyushin, 1978; Popp, 1998; Rubik, 2002b ).
Photon-count statistics on the distribution of photons in the emission should provide an
answer to this question (Kobayashi, Devaraj, and Inaba, 1998; Van Wijk and Van Wijk,
2005). Possibly, both schools of interpretation are only partly correct because the
biophoton emission may be a mixture of signal amidst some noise of free radical
luminescence.
Over the decades of research in this area, several studies have made progress in
investigating human biophoton emission in both basic and applied research. Some
recent results suggest the rudiments of a new powerful tool of noninvasive medical
evaluation on the horizon that will monitor biophoton emissions to assess basic
regulatory functions of the human body. Nonetheless, only a limited number of studies
has been conducted investigating a very limited number of human subjects in these
studies, making any firm conclusions premature. In addition, substantial difficulties
exist in making reliable measurements of such extremely low – level light; thus more
development of measurement technologies will be necessary before systematic studies
can be pursued.
The handling of subjects is also problematic for these studies. Collecting the spatial data
on humans is difficult, which requires that they remain still for a long time, with the risk
that their blood flow may decrease in the process, affecting the biofield that researchers
hope to measure. This risk has been demonstrated by the tourniquet experiment
mentioned previously, which showed the importance of blood flow to biophoton
emission. Moreover, studies also show the importance of subjects’ states of
consciousness, which should also be analyzed along with biophysical and physiologic
correlates of photon measurements.
Toward New Assays for the Human Biofield: Basic Research on Biofield
Therapies
The various biofield therapies may involve key changes in the human biofield and the
transmission of energy field components that are especially important for healing. The
biofield therapies include external qigong therapy, therapeutic touch, Reiki, Johrei,
pranic healing, polarity therapy, and other modalities. Typically, the practitioner uses
his or her hands to sense a deficiency or imbalance in the patient’s biofield and then
proceeds to alter or influence this imbalance by means of a subtle energy. The various
biofield practices coevolved with different ideas about the origin of the energy
transmitted and the role of the practitioner. In external qi therapy and polarity therapy,
the energy is thought to move from the practitioner’s body to the patient. In Reiki,
Johrei, and therapeutic touch, the energy is considered to come from universal source
(the cosmos, divinity, and so forth) to patient, guided by the practitioner, who is viewed
only as a conduit.
Studies on these biofield therapies in themselves may offer clues to certain key
components of the human biofield that are associated with healing. A key study by
Syldona and Rein (1999) suggests that the direct current (DC) potential of the
acupuncture meridian system is a key component in the flow of qi in the body and is
discussed later. An important factor to keep in mind is that these studies may show
either the effects of an energy field associated with the human biofield of the
practitioners or the effects of a universal life energy source on which they may draw, or
some combination of both. Also possible is that the living targets of these biofield
therapies may respond more to putative energies that are not measured by laboratory
instruments.
Published studies demonstrate some definite effects from biofield therapies on various
target instruments or living systems in the laboratory. Most of these studies have been
in pilot studies with small numbers of practitioners as the human subjects. However,
with few exceptions, the studies have shown small effects in magnitude and rather high
variability. When practitioners trained in the same biofield therapy are studied in the
laboratory, a great deal of variability results in their effects on target instruments,
organisms, or humans. In addition, difficulty has been found in reproducing results with
the same practitioner over time. The source of this variability is not well understood, but
one hypothesis is that it may be the result of differences in mood or physiologic states of
the practitioners (Rubik et al, 2006 ). That the different levels and range of experience
of the practitioners may also contribute significantly to the variability of results is also
possible. Although Reiki offers a certification program, many other practices do not
have any standardization. This lack of standardization causes further difficulties for
research on biofield therapies.
These findings from basic research, if replicated by others and further developed and
standardized as tests, may also prove useful as assays or bioassays to measure the level
of bioinformational energy delivered by human hands. In this way, we may learn more
about the healing modes of the human biofield and how it interacts with the cellular and
biomolecular levels of order. Ideally, researchers should have more objective standards
for calibrating the healing power of a biofield practitioner. Some recent studies on
biofield therapies are discussed briefly he re.
External Qi
A body of literature has been published on the effects of external qi transmitted by
qigong therapy practitioners on living systems in vitro, including effects on cell cultures
and biomolecules. However, some of these studies lack critical controls, involve only a
single qi-emitting practitioner, or use outdated technologies. Nonetheless, some recent
improvements have occurred in the quality of research in this area. One key example is a
study done at the Walter Reed Research Institute that used a fluorescent probe to
measure changes in intracellular free calcium concentration associated with emission of
external qi, which is apparently the result of changes in cell membrane channels (Kiang,
Ives, and Jonas, 2005). Another example is a study conducted at a university in Taiwan,
showing that exposure to external qi significantly decreased the growth rate of prostate
cancer cell cultures as compared with untreated cell cultures (Yu, Tsai, and Huang,
2003). Moreover, the authors showed that the treated cells showed increased
differentiation, as indicated by the expression of a tissue-specific enzyme. A third
example is a study conducted in academic laboratories in both China and the United
States, indicating that external qi caused a small change in the circular dichroism
spectrum of poly D-glutamic acid, which may reflect a change in the secondary structure
of the polypeptide (Chu et al, 2001). These studies use some of the latest biomolecular
techniques with high specificity to show how external qi may interact and cause changes
in living systems.
A series of studies on the effect of external qi therapy on cultured brain cells was
conducted in China (Yount et al, 2004). Proliferation of normal cells in culture was
quantified as colony-forming efficiency (CFE). In a pilot study with eight experiments,
results show a trend toward increased cell proliferation in the samples treated by
external qigong therapy (qigong/sham CFE ratio > 1.0). A statistically significant trend
of increased proliferation after qigong treatment was also found in a subsequent study
with 28 experiments. However, in a further study with 60 experiments to replicate the
previous studies, results showed a nonsignificant but slight increase in proliferation
after external qi treatment. When the results from all three studies were pooled to form
summary statistics, including an overall t-test for significance, the mean for the
qigong/sham data was above 1.0 but not statistically significant (Yount et al, 2004).
Measurements of DC potentials on the skin of qigong healers was made for different
states of being, including external focus, healing at a distance (external qi), and self-
healing (internal qigong) (Syldona and Rein, 1999). The authors found a statistically
significant difference between the rate of changes in the values of electrodermal
measurements on and off acupuncture points and between external focus and healing
states. They also found that subjects’ self-reported sense of the internal flow of qi
correlated with DC potential readings but only for specific measurements made on
acupuncture points. Their results showed no clear distinction between external and
internal qigong. These findings support the hypothesis that the patterns in the temporal
fluctuations of the DC electrodermal acupuncture measurements correspond to the
traditional Eastern concept of qi circulating in the body.
Therapeutic Touch
Evidence was found of shifts in the magnetic field emitted by practitioners performing
therapeutic touch, as measured by a SQUID magnetometer (Seto, et al, 1992). In a
subsequent study, the biomagnetic component of a therapeutic touch practitioner
showed a field with a variable frequency around 8 to 10 Hz (Zimmerman, 1989). These
studies suggest that the 8- to 10-Hz frequency band may be associated with emission
from the human biofield during this therapeutic intervention. Interestingly, this
frequency band is also the alpha rhythm of the brain during relaxation and part of the
natural resonance frequency bandwidth of the earth, known as the Schumann
resonance.
Another study investigated the effects of therapeutic touch on bone cells in culture
(Jhaveri et al, 2004). It significantly stimulated primary human osteoblast proliferation,
matrix synthesis, and mineralization compared with controls. Other studies with human
osteoblasts revealed that therapeutic touch stimulated normal human osteoblast
adhesion, with significant changes in integrin levels. Additional work has shown a
significant increase in fibroblast, osteoblast, and tenocyte proliferation with therapeutic
touch treatment, with different dose-response curves to therapeutic touch dependent on
cell type. These data were confirmed by immunocytochemistry.
Reiki
A portable three-axis digital gaussmeter, which can detect milligauss levels of magnetic
fields (AC and DC), was used to monitor Reiki practitioners (n = 17) and healers from
several different healing traditions ( n = 15) who were instructed to transmit biofield
therapy. Highly significant increases in extremely low – frequency (ELF) fluctuations
were observed compared with baseline controls and were observed for both hands of
practitioners. Moreover, significantly larger increases in ELF fluctuations were observed
with more experienced practitioners. Thus changes in ELF magnetic fields were
correlated with the practitioner’s sense of biofield manipulation (Connor and Schwartz,
2007). In a separate study that attempted to develop a literal bioassay for biofield
therapy (using organisms as the measuring instrument), Reiki treatments on the growth
of bacterial cultures (Escherichia coli K12) that had been damaged by heat shock
treatment were analyzed along with a determination of the influence of healing context
and practitioner well being on such effects. In the healing context, the Reiki-treated
plates exhibited an average of 2.6% more colonies than controls in 59% of the trials.
Practitioners’ social and emotional well being correlated with bacterial growth in both
the healing and the nonhealing contexts (Rubik et al, 2006).
Pranic Healing
Dr. Joie Jones conducted studies on the effects of pranic healing on cultured cells at the
University of California, Irvine, over many years (Jones, 2001). Using a bioassay with
HeLa cells (a cell line derived from cervical cancer cells taken from Henrietta Lacks, who
died from her cancer in 1951) in culture subjected to gamma radiation, the radiation
survival rates for the cells with and without pranic healing were determined. To date,
520 experiments have been conducted of 10 culture dishes each involving 10 different
pranic healers. Results from 458 of the experiments indicated that treatment of the cells
with pranic healing produced a dramatic increase in cell survival rate, from
approximately 50% in control cells to approximately 90% in treated cells. In 62
experiments, however, the healer produced no effect whatsoever. Jones noted that a
subtle energetic conditioning of his laboratory contributed by the practitioners led to a
stronger beneficial effect from pranic healing. Collectively, these experiments suggest
that the condition of the energy environment in which studies are conducted may
contribute to the variability of responses (Jones, 2006).
Some Key Issues — Complications in Validating Biofield Measurements But a
New Dimension in Prognosis
Some anticipated complications have been discovered in seeking correlations between
biofield measurements and conventional physical diagnoses. One problem is that
biofield measurements assess energetic aspects of the body, which may either precede
physical changes or possibly correlate with the present physical status of the body. Thus
one may observe putative false positives in biofield indicators that actually reflect a
pathologic process that has not yet developed in a measurable disease state or
physiologic condition. This factor is in concordance with the principle of oriental
medicine that blood follows qi; that is, the physical body will change according to the
present status of the biofield. Second, one may also observe false positives (that is,
failure to correlate with conventional diagnoses) for minor problems, particularly
transient ones, of which the patient may be only minimally aware, or for conditions that
may be subclinical or not yet fully resolved. Nonetheless, various biofield measures,
such as the MSA, are believed to have predictive value for the appearance of disorders
and diseases before they physically develop, allowing preventive action to be taken. The
situation is similar to the status of certain conventional biomedical markers, such as
blood levels of C- reactive protein, which may appear elevated during the course of a
cold as a result of a virus, as well as a serious chronic degenerative disease such as
cancer. Third, certain aspects exist to the biofield that may fluctuate rapidly such that no
reliability in measurement may be seen, which may be the case for certain subjects more
than others. Repeated measurements may yield different values because the subject’s
energy may be rapidly shifting. Such variability may be expected in subjects with poor
energy regulation.
Interpreting any single clinical finding without observing a constellation of evidence is
generally inappropriate, which, taken together in a clinical context, points to a definitive
result. In any case, we anticipate that biofield measurements may not be definitive but
will add yet another dimension to the clinical picture and the resolution of the health
problems of a patient.
Because of these various complications, biofield measurements, in themselves, may
never screen or diagnose populations reliably for disorders and diseases. Nonetheless,
comparing biofield measurements of a specific subject over time may show meaningful
changes that relate to the person’s state of health and may even provide evidence of a
developing pathologic abnormality. The latter is known as an ideographic approach in
the field of psychology. Such a method is applied in medical thermography, for example,
to assess for changes in breast thermograms over time that may reflect a developing
cancer. Thus an ideographic approach may be a more useful method in biofield science
than the conventional scientific nomothetic approach, which is the quest for lawlike
regularities in the study of large numbers of subjects. In CAM, which uses many
individualized, as well as multiple, therapies to treat conditions and diseases, the
ideographic approach may, in fact, be the only meaningful method.
The possibility also exists that the biofield will shift because of transient thoughts or
feelings of the patient. In relation to this phenomenon, certain patients under medical
examination exhibit white coat hypertension that yields a false-positive result for
hypertension. Can we see a relationship between the transient shifts in biofield
parameters and shifts in consciousness of the patient? Should we be investigating this
spectrum, which may represent the dynamical mind-body spectrum for the patient?
Another possibility is that the biofield of some patients will shift with the thoughts,
intent, or feelings of their practitioners. Findings suggest resonance effects occur in
therapeutic partnerships between patient and practitioner (Caldwell-Bair, 2006).
On the other hand, an advantage can be found to observing indicators of the future state
of the patient energetically using biofield measurements. That is, by the principle of
oriental medicine that blood follows qi, positive changes observed in the biofield after a
medical intervention may be expected to correlate with a therapeutic benefit from that
intervention. In this way, biofield measurements may be useful prognostically, as well as
diagnostically.
The primacy of the biofield over the material body, a belief held by many people since
ancient times, means that the material aspect of the body is subordinate to the energetic
and not the reverse. All disease may show first via imbalances in the biofield. Self-
healing involves changing the biofield, which then organizes changes in the tissues at
the deepest levels of the biochemistry. This concept is a radical departure from the
conventional biomedical view that holds biochemistry to be the prime mover.
Conclusions and Prospects for the Future
An overview of biofield science with respect to human biofield measurement and
application to CAM was provided in this chapter. A growing body of basic science data
can be found, preliminary and pilot studies, that provide support for the concept of a
biofield. Further theoretical and experimental research is needed to refine and
standardize the measurements of the biofield, develop new techniques, explore its
relevance to health, disease, and healing, and otherwise continue to explore this frontier
area. Three categories of biofield measurement from humans have been reviewed: (1)
high-voltage electrophotography, (2) EDT, and (3) natural light emission (biophotons).
EDT is more clinically useful than the other methods, whereas the GDV camera and
biophoton measurements are largely still tools for exploration in basic and clinical
research, with fewer clinical applications.
Indeed, the data taken collectively from these explorations reveal that the human
biofield is as a flickering flame of energy: dynamic, with some coherence and stability
and with some elements of chaos and unpredictability.
The lack of validated measurement tools and energy markers remains an obstacle to
progress in biofield science and medicine. The peer-reviewed literature, at least in
English, reveals no biofield instruments to date that have been well documented or
generally approved by the research community. No substantial database of conditions
and diseases correlated with any energy field measures of the human body has been
published. Reliability and validation studies are scarce. No device has been consistently
shown in controlled trials to produce energy field measurements that correlate well with
diagnoses or therapeutic effects. Moreover, some of the commercial devices for
measuring biofield components have algorithms for data analysis or interpretation that
remain obscure or only vaguely revealed. Thus, in many cases, the parameters derived
from raw data via the software and their significance are unclear. More work is needed
to bring the technology into greater acceptance for both research studies and the clinic.
A large influx of funding for biofield science is recommended to support a concerted
effort over the long term by a larger community of collaborating scientists. Work in
isolation by only a handful of researchers is insufficient to bring this work to full
fruition.
Besides refining the techniques, future research approaches should include, but not be
limited to, the physical characterization of the biofield, examination of mechanisms
down to the cellular and molecular level for sensing and studying the emissions of the
biofield, and the influence of psycho-logic and physical states on these processes.
The study of the mutual coupling of fields and radiative emissions on the one hand with
biomolecular processes on the other, or otherwise stated, the intersection of biofield
science with biochemistry, is a key research challenge for the future. Once we clearly
identify the various modes of this coupling, our understanding of energy medicine and
other CAM therapies, and indeed of life itself, will move to a new level.
Also at the cutting edge of biofield research is the question of how the biofield may shift
as a result of shifts in consciousness. Understanding more about the human biofield in
connection with psychophysiologic states such as healing and altered states might help
facilitate an understanding of mind-body regulation and help build a bridge between
energy medicine and mind-body medicine.
